Offer letter: what it commits you to, and what it should not
An offer letter is the moment the terms become real. Conditions that are not in it cannot usually be added later, and promises made in it are hard to take back.
A master service agreement holds the terms that never change so each project can be a short order. What belongs in the MSA and what belongs in the statement of work.
A master service agreement — an MSA — is the contract you sign once with a supplier or a client so that every subsequent piece of work can be commissioned in a page rather than renegotiated from scratch. It carries the terms that do not change from job to job: liability, intellectual property, confidentiality, payment terms, termination. The individual work goes underneath it, usually as a statement of work, and the split between the two is where most of the value and most of the mistakes live.
The order of precedence clause is the one nobody reads and everybody eventually needs. State plainly whether the master agreement or the individual order wins when they conflict. The usual answer is that the master wins except where the order expressly says it is varying a named clause — which stops a project manager from accidentally rewriting your liability cap in a scope document.
Ettex Signature handles the signing and keeps the executed version with its date and signatories, which is what you need when someone asks two years later which terms were in force. Keep every order under it linked to the same record rather than filed by project, so the question "what have we agreed with this company in total" has one answer. Where volumes grow past what one person can track, contract management software is the next step, and the renewal dates are usually what forces it. Ettex does not draft agreements and this is not legal advice — an MSA allocates real risk and is worth a lawyer’s time.
Usually not — a single contract is simpler. The MSA earns its cost from the second engagement onward, and it is worth putting in place as soon as a relationship looks like it will repeat.
Whoever drafts sets the defaults, and defaults survive negotiation more often than people expect. If you are the supplier and can offer a reasonable standard agreement, do — it saves weeks and usually lands closer to your position.
In practice they overlap heavily. A framework more often implies multiple suppliers and a call-off procedure, particularly in public procurement, while an MSA is normally bilateral. The mechanics — fixed terms, individual orders underneath — are the same.

An employment contract exists whether or not anyone signs paper. Writing it properly is how you control what the unwritten version would have said.
A promissory note is a written promise to pay a fixed sum. Whether a court will enforce it comes down to a handful of terms most templates get wrong.
